How can we help?

What is the Line2 Gateway and why does it show up when I place a call?

The Line2 Gateway is a system number that is used to place outbound calls via your cellular voice network when a VoIP call is not possible because an internet connection was not available.

If you are trying to place a call via Line2 and see the app redirect to dialing Line2 Gateway, this means that Line2 was unable to locate a working WiFi or cellular data connection (3G/4G or LTE) and is attempting to place the call over your cellular voice plan.
